名词
一.名词的数
可数名词在应用时有单数与复数的区别,表示一个用单数,两个以上用复数。名词复数形式是在单数
名词后加-s -es 构成的。另外,表示不可数名词的量,用容器的量来表示,即单位+of +物质名词的形式,
a cup of coffee(一杯咖啡)
名词的数
单数 a bird(一只鸟)
an egg(一个蛋)
复数 three birds(三只鸟)
many eggs(许多蛋)
1.单数
英语中,如果我们要表示一本书、一只鸟、一棵树等概念时,要用名词的单数形式,表示名词的单数,
要在名词前加冠词 aan
This is a desk .这是一张书桌。
There is an orange on the table .桌上有一个橘子。
an orange 一个橘子
aan 的使用区别
a加在以辅音开头的名词前,如 a booka pen
an 加在以元音开头的名词前,如 an eggan apple
注意
有时 aan 后面紧接的不是单数名词,而是 a (an) +形容词+单数名词的形式。这时判断用 a还是 an 来表示
一个的概念时,要看形容词开头字母的发音,而不是看名词。
2.复数
英语中,如果要表示两本书、三个学生、四把椅子这些两个或两个以上的概念时,要用名词的复数形
式,名词的复数形式是在单数名词后加上词尾-s -es 构成的。
1
These are books.这些是书。
There are many tomatoes on the table.桌上有一些西红柿。

c.以辅音字母加 y结尾的单词把 y变成 i-es

注意
以元音字母+y 结尾的名词单数变复数时,y不变,直接加 s。如:day→days
d.ffe 结尾的,去掉 ffe,变 ves
leaf→leaves life→lives knife→knives
例外 roof→roofs
2.不规则变化的复数形式
